ABRAHAM SMITH, or WHEELERS enovn, io wA- IMPROVEMENT IN GRAlN-DUMPING DEVICES.

Specification forming part of Letters Patent N0. 199,112, dated January 8,1878; application filed September 1, 1877.

To all whom it may concern Be it known that I, ABRAHAM SMITH, of Wheelers Grove, in the county of Pottawattainie and State of Iowa, have invented anew and valuable Improvement in Grain-Dump; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a side view of my grain-dump. Fig. 2 is an end view. Fig. 3 is a sectional detail; and Fig. 4 is a detail thereof.

The nature of my invention consists in the construction and arrangement of a machine for transferring corn and grain from wagons to a crib, as will be hereinafter more fully set forth.

The annexed drawings, to which reference is made, fully illustrate my invention.

A A represent two parallel bed-sills, of suitable length, connected by cross-bars and mounted upon rollers or wheels B B, so that the entire machine may be moved from place to place as required.

Upon the sills A A are erected four uprights, 0 0, connected at the top by a frame, D, and held firmly in proper position by means of braces E E, substantially as shown.

The uprights 0 form ways, between which a frame, G, is moved up and down, said frame containing the-transfer-box G. This box is hung upon pivots or journals a a in the frame G, and its front end provided with a crossbar, 11, connected to it by links I) b. This cross-bar has a vertical bar, I, extending upward'through a cross-bar in the frame G, with a pin, d, through its upper end. This pin limits the downward movement of the front end of the box, and holds it in a proper position for the discharge of the corn or grain therein. The front of this transfer-box may be raised, and the box held in a horizontal position by means of a spring-latch, h, entering a notch, t, in the bar I. By simply pressing back this latch the front of the box will fall down until the pin d strikes the cross-bar of the frame G.

-At the front of the box G is hinged achute or mouth, G which may be thrown up and fastened by a latch, f, while transferring the grain.

The frame G is operated bymeans of a windlass, K, from which a rope or chain, 7c, passes over and around pulleys, substantially as shown in Fig. 4.

Between the bed-sills A A is arranged a sort of bridge, over which the wagon passes to dump the load into the transfer-box G. This bridge consists of an upward incline, made in two parts, L and L, a horizontal platform, L and a downward incline, L

The part L of the first incline is stationary,

and reaches to the first set of uprights; The other part, L, of this incline reaches to the next set of uprights, and is hinged at its lower end, so as to be thrown upward in a vertical position and allow the transfer-box to descend below the platform L In this platform are two dumping-bars, m m, which are held in a horizontal position, flush with the upper surface of the platform, by means of arms omprojecting from a rocking bar or shaft, -n, operated by a lever, W.

The wagon is driven up the inclines L L onto the platform L The incline L is then raised and the transfer-box lowered with its frame, it being, of course, understood that at this stage of the operation the box G is horizontal in the frame G and the mouth G raised and held by its latch.

The hind wheels of the wagon being placed on the dumping-bars m m, the arms 70 'n, are withdrawn and the wagon dumps so as to de posit its load in the transfenbox. As soon as this is done the wagon is driven down the incline L which raises the bars m m, and the arms a n are at once turned under the same.

The transfer-box is then, by means of the Windlass and rope, raised to the desired height, and the contents then discharged, as above described. The incline L is let down and the next load driven onto the platform L and the same operation repeated.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for transferring grain, a movable frame, G, having a transfer-box, G, hung upon journals a a in the frame G, andits front end provided with a cross-bar, H,ineom- In testimony that I claim the above I have bination with a vertical bar, having a pin, 11, hereunto subscribed my name in the presence substantially as and for the purpose set forth. of two Witnesses.

2. The combination of the frame G", the journaled boX G with hinged mouth G T-shaped ABRAHAM SMITH' arms H I, with pin d, spring-latch h, and latch Witnesses f, all substantially as and for the purposes set G. B. OTTO,
